Description

Technical Field

[0001] The utility model relates to the technical field of gas pressure monitoring and vacuum monitoring devices, and particularly relates to a gas pressure and vacuum degree monitoring device. Background Technique

[0002] Gas is the general term for gaseous fuels, which can burn to release heat and is used by urban residents and industrial enterprises. There are many types of gas, mainly including natural gas, artificial gas, liquefied petroleum gas, biogas, etc. Due to the high calorific value of gas and less environmental pollution of combustion products, it is considered a high-quality clean fuel. It can not only be used as domestic fuel for residents, but also as fuel for vehicles and other means of transportation. With the continuous increase in the demand for gas by people, the gas pipelines for transporting gas in cities are becoming more and more dense and complex. Therefore, higher requirements are put forward for gas monitoring and maintenance.

[0003] At present, gas monitoring devices are commonly used in the market to monitor and analyze the pressure in the gas detection cavity at different time points, so as to obtain information such as whether there is an abnormality in the gas pressure and the type of abnormality. On this basis, corresponding maintenance operations are carried out on gas equipment to ensure the safety of gas supply and gas equipment, and thus ensure the life and property safety of the people. Among them, common gas pipeline safety monitoring devices are used. However, ① in the gas pressure monitoring and vacuum pressure monitoring system, separately reserving a vent pipe orifice will increase the complexity of gas pressure monitoring and vacuum pressure monitoring; ② at the same time, in the above gas pressure monitoring and vacuum pressure monitoring devices, pressure gauges are used for pressure monitoring. Since the slight deflection of the pressure gauge pointer is often not easily noticed, there are serious safety hazards.

[0004] Therefore, how to design a gas pressure monitoring and vacuum pressure monitoring device with simple structure, low preparation cost, low installation cost and high detection accuracy is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0005] The utility model provides a gas pressure and vacuum degree monitoring device, which solves the technical problem that installing a gas monitoring device will greatly increase the complexity of the gas supply pipeline.

[0006] The technical solution of the utility model to solve the above technical problems is as follows: a gas pressure and vacuum degree monitoring device includes: a housing, a gas pipe, a vacuum three-way pipe and a detection chip.

[0008] The beneficial effects of the present utility model are as follows:

[0009] 1. By changing the installation method of the traditional gas pressure monitoring device, first open a ventilation hole on the pipe wall of the gas pipe, and then open a first detection hole on the top end of the housing that is in relative communication with the ventilation hole. Since the pipe wall of the gas pipe is sealed and fixed at the top end of the housing, it is possible to avoid separately reserving a gas pipe orifice in the original gas pipeline system, simplify the structural layout of the gas pipeline system, reduce its complexity, and reduce its manufacturing cost and installation cost;

[0010] 2. First, use the vacuum tee to communicate with the vacuum pipe outside, and then use the detection chip to detect the vacuum degree in the detection chamber. Since the vacuum tee is communicated with the detection chamber, the detection chip can be used to detect the vacuum degree in the detection chamber, improving the detection accuracy and detection safety.

[0011] 3. Use the detection chip to replace the traditional pressure gauge and vacuum detector, avoid the situation where the slight deflection of the pressure gauge and vacuum detector is not noticed, improve the accuracy of gas pressure monitoring and vacuum degree monitoring, and protect the safety of people's lives and property.

[0012] Based on the above technical solutions, the present utility model can be further improved as follows.

[0013] Further, the housing includes a top cover and a bottom cover. The open end of the top cover is arranged downward, and the open end of the bottom cover is arranged upward. The open end at the bottom of the top cover is detachably and sealingly connected to the open end at the top of the bottom cover; the detection chamber is the internal area between the top cover and the bottom cover; both the first detection hole and the second detection hole are provided at the top end of the top cover; the pipe wall of the gas pipe is sealed and fixed at the top end of the top cover; the detection chip is fixed on the top cover or the bottom cover.

[0015] The further beneficial effects of adopting the above are as follows: Embedding the gas pipe in the fixing groove can improve the sealing performance between the gas pipe and the top cover, preventing gas leakage.

[0016] Furthermore, the longitudinal section of the fixing groove is semi-circular.

[0017] Furthermore, a plugging cylinder is fixed on the outer peripheral side of the top cover corresponding to the second detection hole; one outlet end of the vacuum three-way pipe is detachably plugged in the plugging cylinder and communicated with the detection cavity.
